How New Jersey Income Tax Works

New Jersey taxes income progressively: lower portions of income are taxed at lower rates, and higher portions at higher rates. Rates range from a low percentage on the first tier of income up to higher rates on income in the top brackets. Your total state tax is the sum across all the brackets your income spans.

NJ-Specific Payroll Items

New Jersey withholds for several state programs beyond income tax, including unemployment insurance (UI), temporary disability insurance (TDI), and family leave insurance (FLI). These small contributions reduce take-home pay and are specific to New Jersey workers.

Note: This is an estimate. Your actual tax depends on current rates, deductions, credits, and your full financial situation.
